Product Description
Webb 56864B 16.5 x 7 Balanced CRT Brake Drum
The Webb 56864B is a balanced 16.5 x 7 heavy-duty brake drum designed for standard-duty drive and trailer wheel ends. It features Webb CRT (Cool Running Technology) vents that increase airflow through the wheel end to improve heat transfer and help control brake operating temperatures.
Webb redesigned the 56864B with its patented CRT vent system to run approximately 10% cooler and provide approximately 10% longer service life than comparable similar-weight brake drums. It is rated for drive and trailer wheel ends up to 23,000-lb GAWR.
The 56864B uses a 10-hole outboard mounting configuration with an 8.78-inch pilot and 11.25-inch bolt circle. Webb manufactures its brake drums in the USA.
